Item 2
Suppose chocolate costs $17.60 per kilogram. Karega buys 25 grams of chocolate and Samadhi buys 100 grams of chocolate.

How much more did Samadhi pay for her chocolate?

$0.44

$1.32

$2.20

$2.64

$1.32 more.

Step-by-step explanation:

To calculate this, remember that there are 1000 grams in one kilogram.

So, Karega bought 25 grams, which is 25/1000 kilograms (or 1/40)

Samadhi bought 100 grams, which is 100/1000 kilograms (or 1/10)

Therefore, you can multiply 17.60 (the price per kilogram) times each fraction that they bought.

17.60 * 1/40 = $0.44

17.60 * 1/10 = $1.76

You then subtract 1.76 by 0.44 to find out how much more Samadhi paid than Karega, which is 1.32.
